“…To do this, Multiphysics FEM analysis is widely used to calculate the thermalmagnetic coupling problem in the field of induction heating. A gear was modeled and analyzed to obtain temperature distributions in the model by magnetic-thermal coupled analysis [10,11]. Przylucki and Smalcerz analyzed a 3D gear model with pulsing dual frequencies beyond a conventional induction hardening using a single frequency [12].…”

This paper presents the development of a simultaneous dual frequency (SDF) induction hardening apparatus for gear hardening process. First, 2D FE modeling for thermal-electromagnetic coupled field is introduced for gear hardening and the analytical results are investigated. By modeling the gear hardening as 2D FE model, we can calculate for the coupled field more efficiently. And optimum process parameters can also be found through this analysis. A real SDF heat treatment equipment is manufactured using analytical results like input frequency and gear hardening experiments are conducted. Through analysis and experiments, we can validate the performance of the developed machine.

The relative permeability and electrical conductivity of the pan material, both of which vary with temperature, play an important role in thermal power of induction cooker system. A series of finite element models, including a variable relative permeability electromagnetic model, a variable electrical conductivity electromagnetic model, and an electromagnetic and thermal coupling model, have been built by ANSYS software to analyze the variation of the thermal power with relative permeability and electrical conductivity in this paper. It is indicated that thermal power increases with the relative permeability increasing, but its growth rate decreases. When the electrical conductivity increases, thermal power increases, reaches a peak value, and then decreases. Considering the variation of the relative permeability and electrical conductivity with pan temperature, the simulation results show that thermal power decreases a lot when the temperature of the material exceeds a definite value due to the low relative permeability in this case. Finally, the induction heating mechanism is clearly understood and the simulation results provide useful guidance for induction cooker design.

This paper investigates a 3-D coupled-field finiteelement method (FEM) used in simulation of temperature distribution in air-cooled asynchronous induction motor. The temperature rise in motor is due to Joule's losses in stator windings and the induced eddy current in squirrel cages, and heat dissipation by air convection and solid conduction. The Joule's losses calculated by 3-D eddy-current field analysis are used as the input for the thermal field analysis, which is deeply dependent on accurate air fluid field analysis. A novel multicomponent fluid model is proposed to deal with the influence of rotor rotation upon the air convection. Through the coupled-field calculation, we propose a new ventilation structure of a 15-phase motor to improve the cooling performance.
